A vertical slot fishway and two Denil fishways (of 10 and 20% slope) built into 
a weir on the Lesser Slave River (55o 18'N, 115o 45'W) were studied from May 12 
to June 25, 1984, to determine how effectively these designs pass north-
temperate, nonsalmonid fishes. Thousands of spottail shiner Notropis hudsonius, 
substantial numbers (> 100) of northern pike Esox lucius, longnose sucker 
Catostomus catostomus, white sucker Catostomus commersoni, immature yellow perch 
Perca flavescens, and lesser numbers of burbot Lota lota, adult yellow perch, 
lake whitefish Coregonus clupeaformis, and trout-perch Percopsis omiscomaycus 
ascended the fishways. Walleye Stizostedion vitreum and goldeye Hiodon 
alosoides, although probably moving extensively through the river, did not use 
the fishways.
